摘要: The present invention relates to a tracking picture tube of the type in which comb-shaped electrodes or optical detecting means (12, 13) are used for generating a signal related to the position of an electron beam with respect to the strips (5). The tube is characterized in that the deflection unit is arranged to deflect the beams (21r, 21g, 21b) onto selected strips (22r, 22g, 22b) having coincident sides which neighbour finger portions (14, 15) of the same electrode (12, 13), and the selected strips (22r, 22g, 22b), excited by the electron beams, are separated by at least one unexcited strip, respectively.

摘要: By incorporating two-pole circuits (13) as switching elements in a picture display device based on field emission, the emission (and hence the picture intensity) is substantially defined by the charge of a capacitance (15) associated with a part of a pixel (8). Charge-controlled drive leads to a more accurate adjustment than the voltage-controlled drive used until now and leads to lower drive voltages, less power consumption and a longer lifetime of the phosphors used in the display device.
